OSR Unhinged was developed by Riddlersoft and released on December 16, 2010 for 80MSP. A copy of the game was provided by the developer for review purposes.

OSR Unhinged hearkens back to the pre-Trials HD days; days where Elasto Mania and Dirtbike ruled the motorcycle physics game genre. The very soul of this game screams that it belongs in Newgrounds or some other flash-based game community, but at the same time it takes a page from its 3D brothers. It's a simple, fun game that provides a lot of content and replay value at a very reasonable price.
